' INKINC MECHANISM.

' My invention relates to inking mechanisms for printing presses and it has for one of-its objects the provision of a new and improved form and arrangement of parts for moving certain of the inking rollers out of operative position when the press is out of operation. It is' one of the more specific objects of my invention vto provide means for throwing the form rollers and the vibrating rollers .simultaneously out of contact with the inking cylinder and the forml cylinder. It is another object of my invention to providemeans for driving the inking cylinder independently of the operation of the press whereby the inking cylinder may be brought to a properly inked-up condition prior to a run of the'press. It is another object of my invention to improve mechanisms of this type'in sundry/.details hereinafter pointed out., The preferred means by which I have accomplished my several objects are illustrated in the drawings andare hereinafter specifically described. v That which I believe `to be new and desire to Zoover by this application is set forth in the claims.

.-In the drawings Y Figure1 Vis a view of a portion of a press embodying my improved form of inking mechanism; I f Fig. 2 is avertical cross-section, partly `broken away, through the inking mecha,- nism, being ltaken substantially on line 2--2 of Fig.1; g Fig. 3 is a vertical section taken on line 3-7-3 of Fig. 2; and Fig. .4 is a vertical Section 4 4: Of 2. v

andi'12 by means of links 19 which are con- 'nectedfat their-*lower ends :to the arms 14 and are connected at their upper ends to eccentrics 20 mormted upon a rock-shaft 21 above the cylinder 11, as shown in Fig. 2. Ihe arms 16 arel held in position by means of links' 22 connected at their lower ends with said arms and connected at their upper ends with eccentrics 23 likewise mounted uponv the shaft 21. Theform and arrangement of .the parts is such that the rollers 15 and y17 are adapted to be thrownsimultaneously into engagement with the cylinders. 11 and 12 and are adapted in turn to be thrown simultaneously out of such engagement, the rollers 18 being thrown out -of engagement with the cylinder 11 at the same time when the form roller 17 isthrown out of engagement with the cylinders 11 and 12.

The rock-shaft 21 is utilizedfor supporting a gear 24 revolubly mounted thereon and meshingwith a gear 25 revoluble with the cylinder 12 and also meshing with a gear 26 revolubly mounted upon the shaft 27 by whichthe inking cylinder 11 is supported. rIhe gear 26 is provided with a pawl 28 pivotally mounted thereon adapted to engage a ratchet-wheel 29 keyed or otherwise fixledly mounted uponthe vshaft 27 of the inking-cylinderv 11 so as to drive the ratchet- .wheel and. the'inking cylinder in clockwise ldirection in Fig.v 1. y The pawl28 is pivotally connected by means of a link 80 with a VAcontroller 31 frictionally mounted upon the hub of the ratchet-wheelY 29. By this construction, when the ratchet-wheel 29 is driven in clockwise-direction in Fig. 1 by power-applied thereto independently of the pawl 28,'the friction member 31 is given a slight` rotation in clockwise direction in Fig. 1, servingltolift the pawl 28 out of engagementwith the .teeth of the ratchet-wheel 29. VWhen power is applied to the gear 26 so as to` rotate such Agearin clockwise directionin Fig. 1 relative tothe ratchet-wheelj29, the Ycontroller`31.tends to lag behind, serving to throwuthepawl again into engagement With the .tooth .of .the ,ratchet-Wheel 2.9-

' l32 indicates an inking roller revolubly mounted upon a shaft33 adjacent to the inking cylinder 11. An oscillating roller y34 is adapted to be reciprocated by any suitable means (not shown)A between the inking roller '32 'andthe inking cylinder 11 so as to transfer ink from the roller 32 to f thecylinder 11 in the well understood manner. Ink is adaptedto be supplied tothe roller 32 in the construction shown by a nozzle 35 through a supply pipe 36 from any suitable source, the4 ink-supplying means being preferably actuated bypower from-:the means .by which the roller 32 is .normally driven. A scraper-.blade .37 is provided forspreading the ink .upon lthe roller `32 and for scraping the. surplus. in'k therefrom, any inkso scraped from .the roller 'being adapted .to :fall into a .trough 237%.from which it is .conducted by a'pi'pe 3-8 to -any .suitable point. The inking roller 32-is adapted to be driven by means of a'worm-.gear 39 fixed upon the outer .end of the shaft 339 being driven by a worm 40 fixed upona shaft 41 driven 'by any suitable means in counterclockwise direction in Fig. L2, servingto rotate .the .inking roller 32 .in clockwise direction in Fig.. 1.

` Means is providedv for .driving -the inking cylinder 11 in clockwise direction in Fig. 1 independently Vof the action of the oear 26, comprising a sprocket-gear 42 Xedly connected with the ratchet-wheel 429 connected by means of a sprocket-chain 43 with a sprocket-wheel 44 having clutch connectionsvwith the shaft 33. Theconnections between the sprocket-wheel 44 and the -shaft 33 comprises'a .clutch member 45 revolubly Lmounted upon theshaft and adapted to be driven in .clockwise .direction in Figs. l1 and 4 by a clutch .member 46`keyed or otherwise fixed upon said shaftftheclutch member 45 being adapted to rotate 'in counterclock-wise directionzinFig. 4 independently of the clutch member 46. g Y' Y Y rThe means for driving theshaft 41 is in the' construction shown in the form of a Vplanetary vgearing connected by means of Abevel-gears* 47-43w`ith saidV shaf-t. vThe planetary-'gearing comprises a head 49 adaptedto be driven 'in counter-clockwise direction from any `suitable parti-of Vthe press7 having mounted thereon planetfgears 50-51 meshing with a su1 1gear52 which is connected by meansof a short shaft 53 with `the bevelgear v47. An internal gear l54 revolubly mounted upon fthe axis "of -the sun-gear `52 meshes with planet-gears 530- A5l and is adapted to fbe' driven `lin clckwise direction 'in -Fig, 1' by a -rnotor y55 through vthegmedium yof a worm 56 meshing with suitable worm-gear 4teeth `5,7 formed *upon'the' internal-gear 54.3 f With the-head 49 being driven incounterfinking roller 32 will be driven in clockwise direction in said figure at a rate of about 24 or 25 rotations pei` minute. l/Vith the press running at low speed so that the head 49 will be driven in :the .conntercloclrwise vdilrection in Fig. '-1 at. about 1/.15 the high speed rate, .or l0 revolutions per minute, and with the internal .gear 54 krotating at its normal speed of. 20 revolutionsy .per minute, `the roller 32 will be given approximately 3 l/2 rotations per minute, -or at a rate ;of about 1/7 its speed of rotation when the press is running at full-speed. By the use yof this arrangement a diiferential driving of the inking roller ,32 is secured, .the rol-ler .32 vbeing driven at .a higher speed relative to that Aof the pressv when the ,press is running at low speed .thanwhen the press is operating at its normal high speed. A lVith theninking lcylinder 11 being driven in .clockwise direction in Fig. -1 through the gears 2'5-24f26, and with .the inking .roller 32 being driven in the same direction through the shaft 41, the sprocketfgear 39 is .rotated v.in .clockwise direction vrelative to the slowly-.rotating roller 32,-fthis vresultibeing. attained by reason of .the yielding ofthe clugtch 45-46 When the press is at rest, and the rollers .15,517 and 1 8.have been thrown out .of v.eng-agement @with the cylin- .der 11 and the .cylinder 12, :the .motor 55 is adapted Ato .drive Vthe internal gear 54 in .clockwise direction in Fig. '1, serving to drive the rol-lerf32 at a slow rateindependently of the head 49 :which is maintainedin `fixed. position. 'The clutch 45-46 then serves .to connect the @shaft 33 with the sprocket-wheel 44 for Vrotation of Vsuch sprocket-wheel in clockwise l direction f Vin F'io', 1, whereby l:they sprocket-wheel 42 and inking cylinder l1 are driVenslowl-y 1in clockwise direction in Fig. 1 independently Gifthe remainder of the'press, thepawl 28 being adapted fto permit' rotation noffthe 11-15 ratchet-wheel 29 insuch ay direction relative to the gear 26. i:[n this manner'theroller 32and the inking 4cylinder "11 may -be -rotated and` properly inked up ready'ufor efficient Ioperation of the press prior to i120 starting the press into operation. A Vhatl Iclaim as my invention anddesire :to secure-by Letters Patent,v is-' Y I il. The 'combi-nation of -an inking @cylinderl a form cylinder parallel with said-ink- 125 ing cylinder and out `of f' Contact therewith, two arms swingingly mounted- -relative fto said inking 'cylinder'v Aat its ends, af :form floller' xrevolubl-y mounted .on said -arms Aat one Js'idei ofthe line offcenters of. saidcylinf 'i130 ders, two other arms swingingly mounted relative to said inking cylinder at its ends, a second form roller revolubly mounted on said second-named arms on the opposite side of the line of centers of said cylinders, a rock-shaft extending alongsaid inking cylinder, and links pivotally connected With said arms and having eccentric connection With said rock-shaft whereby upon the turningl of said rock-shaft said form rollers are moved simultaneously either into or out of contact With said cylinders.
